Car rentals for 21st party.

Hi everyone,

My 21st B-Day is coming up on the 17th of April and I would like to have a car themed dinner party. Can anyone possibly tell me where I can rent or hire a few old beemers and mers for the occasion. The party will be held in Randburg. Does anyone know of a company that wont charge me an arm and a leg or maybe a few of the forum members that can assist me? The cars wil only be needed for display at the party.

Thanks guys.
